ABSTRACT OF THE DISCLOSURE Desulfurization of molten ferrous metals such as pig iron is facilitated through the injection of a particulate fluidized mixture of non-oxidizing material and magnesium-containing reactive material by in-line mixing in a conveying line and consequent sub-surface injection. The amount of the contained magnesium, injection time, and contained magnesium injection rate are controlled to maximize process efficiency.
